000 AXPZ20 KNHC 072122 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1948 UTC Sat Sep 7 2019 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...SPECIAL FEATURES... Juliette degenerates into a post-tropical cyclone, and the last advisory is issued by the National Hurricane Center at 07/2100 UTC. At this time, the remnant low of Juliette is centered near 24.4N 129.5W moving toward the W or 280 degrees at 11 kt. Estimated minimum central pressure is 1006 mb. Juliette is still producing a small area of minimal gale force winds, with gusts to 45 kt within 50 nm N semicircle of center, and maximum seas of 15 ft. Deep convection associated with Juliette has ceased, and visible satellite imagery indicates a very well defined swirl of mainly low clouds. A gradual spin down of the circulation is expected with Juliette remaining over waters of 24-25C during the next couple of days. Juliette's motion to the west is expected to continue through the middle of next week, with a gradual decrease in forward speed through Tuesday. See latest NHC forecast/advisory under AWIPS/WMO headers MIATCMEP1/WTPZ21 KNHC for more details. ...TROPICAL WAVES... The axis of a tropical wave is near 106W from 05N to 15N, moving W around 15 kt. Scattered moderate isolated strong convection is noted from 09N to 14N between 103W and 109W. The axis of a tropical wave is near 118W from 04N to 16N, moving W at 10 to 15 kt. Scattered moderate isolated strong convection is seen from 10N to 15N between 115W and 120W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N78W to 10N100W to 13N128W to beyond 11N140W. Outside of the convection associated with the tropical waves, scattered moderate isolated strong convection is observed north of 05N between 80W and 85W, from 06N to 09N between 90W and 96W, and from 07N to 12N between 127W and 131W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge is building west of the Baja California peninsula with NW to N winds across the offshore forecast waters west of Baja. Winds will strengthen north of Punta Eugenia tonight through Sun night, with seas building to 9 or 10 ft near 30N on Sun. Low pressure over the U.S. desert southwest will promote fresh to strong SE to S winds over the northern Gulf of California Sun through Tue. Looking ahead, expect increasing northerly winds across the Gulf of Tehuantepec Wed and Thu as a high pressure builds across the Gulf of Mexico. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Expect moderate to fresh NE to E winds across the Gulf of Papagayo tonight into early Sunday morning, and then again Wed and Thu as a high pressure builds N of area. Elsewhere, mainly light to gentle winds will persist north of the monsoon trough, with gentle to moderate S to SW winds south of the monsoon trough for the next several days. Long-period SW swell up to 8 ft will reach the equatorial zones on Sun through Wed. REMAINDER OF THE AREA... Please see the Special Features section above for details on the remnant low of Juliette. Swell generated by Juliette will produce seas 8 ft or greater over much of the forecast waters N of 20N and W of 125W the rest of today and tonight, and mainly N of 20N W of 130W on Sun. Elsewhere, gentle to moderate NE trades will prevail between a ridge that covers the NW forecast waters and north of the monsoon trough. Little chance is expected over the next several days. $$ GR
